Title: Thermal printer
Inventor: KASHIWAGI TAKASHI
IPC: B41J2/365
Filed: 1994-12-21
Abstract: PURPOSE: To precisely detect a temperature change in a head heating element to improve printing quality by finding a temperature of the head heating element on the basis of a difference between temperatures detected by respective temperature sensors and a function from function storing means. CONSTITUTION: A temperature of a head heating element 1 is predicted on the basis of a temperature difference between a temperature detected by a circuit board temperature sensor 8 and a temperature detected by a heat sink temperature sensor 9 and a function stored in ROM 12. Since the temperature of the head heating element 1 is predicted from a difference between temperatures detected by the temperature sensors 8, 9 provided at locations where temperature gradients are different, it can be precisely detected in the event of performing high speed printing and continuous printing, in which a temperature rise rate of the head heating element 1 is different from those at the locations where the temperature sensors 8, 9 are provided, not to mention the event of the head heating element 1 not varying in temperature.  Accordingly, the temperature of the head heating element 1 can be precisely predicted as compared with indirectly predicting a temperature change of the head heating element 1 by means of a single sensor.
